cldetect – A tool to detect installed software details

What is cldetect?

It is a tool developed by CloudLinux to manage installed software.

It is used to detect installed software, and adjust CloudLinux options accordingly.

As we know, CloudLinux has a lot of options available to manage and tweak Linux servers. We have already covered some interesting topics about Cloud Linux. You can review this category for more articles on CloudLinux.

What is Cloud Linux?

CloudLinux is a Linux based Operating system especially used in a shared environment which isolates each user in its own light weight virtualized environemnts (LVE) which consumes predefined amount of resources allocated for each user. That is, each user will be in a caged environment.

The resource usage of any user won’t affect the stability of another users. Each user will be allocated a specific amount of resources. If a user’s PHP script utilizes the entire resources allocated to it, then it won’t affect other users. Only that particular user will face problems related to this. That particular user will get a “Resource limit reached” error while he access his website. Read more…

Here we go with cldetect options…

Path : /usr/bin/cldetect

You can check the available options by executing the following command:

/usr/bin/cldetect -h

Or 

cldetect -h

To check installed control panel version.

cldetect --detect-cp

[email protected] [~]# cldetect --detect-cp
cPanel,66.0

Other related options..

cldetect --detect-cp-full

Prints control panel, version and panel specific data (CP_NAME,CP_VERSION,...)

cldetect --detect-cp-nameonly

Prints control panel name (CP_NAME)

To print Admin email address of installed control panel.

cldetect --get-admin-email

Output

[email protected] [~]# cldetect --get-admin-email
[email protected]

Advantages of CloudLinux – a detailed view!

There are a lot of advantages on CloudLinux OS over the traditional Linux system. Here, I’m explaining some of them.
1. High stability by controlling the resources for a single user

As we know, this technology is based on LVE (Light weight Virtualized Environment). Each user in the server will be in a caged environment.

2. High server security

With CageFS enabled in CloudLinux based servers, the data/information of a user won’t be available to other users. Read more…
